IMPROVEMENT IN PUMPS.

Specication forming part of Letters Patent No. 187,53 l, dated February 20, 1877 application led August 8, 1876.

To 00H whom it may concern:

Be it known that I, B. J. C. HOWE, of Syracuse, in the county oi" Onondaga and State of New York, have invented a new and useful Improvement in Pumps, which improvement is fully set forth in the following specification, reference being had to the accompanyiu g drawings.

The object of my invention is to construct a pump that will cause a steady and continuous stream of Water or other liquid to tlow without the use of an air-chamber or other device to regulate the tlow of water.

In the accompanying drawings, Figure 1 is an outside view of the pump. Fig. 2 is a longitudinal section of the working chambers, pistons, and valves of the pump. Fig. 3 is a transverse section of the working-chambers. Fig. 4 is an end` view of the triple crank and Consequently, a large amount of friction is avoided.

The three cylinders are arranged, as shown in Fig. 3, in the :most compact manner, so that they can be inserted in a bored or drilled well.

lt will be seen, by witnessing the operation of this pump, that the working of one piston is followed so closely by vthe working ot the next that there is never any cessation in the flow of the water; and also that no two of them are ever working at full` power at the same time. Consequently, while it requires more power to operate this pump than it would to operate a single-piston pump ot' the saine size and length of stroke, yet this pump will throw three times the alnount'of water. The reason that but little more power is required is that in this pump the power is applied steadily and continuously, while in a singlepiston pump the same amountot' poweris unsteadily applied, and only one-third of the amount of water thrown.

y It is evident that the working-chambers may be reversed, so that their open end shall ,be uppermost, and the water forced downward by theaction of the pistons,'instead ot' lifted, as shown inFig. 1, with substantially the same results, which I regard as but a modlication of my invention.

I am aware that pumps of three cylinders,

operated t, by three cranks, are not new; but
